Easy & Tested: How to Get Feces Out of Slow Cooker

Immediate Action (first 5 minutes)

Finding feces in your slow cooker is a visceral shock. Whether your cat decided the Crock-Pot was a new litter box while you were at work, or a toddler had a spectacular accident during a dinner party, your first five minutes dictate the success of the cleanup. Grab your gloves. You're going to need thick nitrile ones, not the flimsy latex kind that snap when you stretch them over your knuckles. I learned that the hard way during a particularly nasty diaper blowout cleanup back in 2018.

Next, isolate the appliance. Unplug the heating base immediately if it's still connected to the wall. Do not add hot water. Hot water coagulates the proteins in feces, essentially baking the biological matter into the microscopic pores of the ceramic stoneware. Instead, use a plastic putty knife or a silicone spatula to scoop out the bulk of the solid matter. Wrap the waste in heavy-duty paper towels—I swear by Bounty Quilted because cheap brands disintegrate when wet—and seal it in a plastic grocery bag. Get it outside to your main trash bin right away so the odor doesn't permeate your kitchen.

What You'll Need (tools/products)

You can't just use regular dish soap for this. Feces contains uric acid and complex proteins that require specific chemical breakdowns. I've tested dozens of cleaners on my own appliances over the last decade, and this is the exact loadout I recommend for biohazard kitchen cleanup.

Item	Specific Brand/Model	Estimated Cost	Why You Need It
Enzymatic Cleaner	Nature's Miracle Urine Destroyer	$15-25	Digests uric acid crystals that cause lingering smells.
Degreasing Spray	Dawn Platinum Powerwash Dish Spray	$6	Lifts residual fats and oils without heavy scrubbing.
Scrub Brush	Fuller Brush Soft Bristle Dish Brush	$8	Cleans effectively without scratching the ceramic glaze.
Disinfecting Wipes	Lysol Disinfecting Wipes (Lemon)	$5	Safe for wiping down the exterior heating base housing.
Odor Absorber	Arm & Hammer Baking Soda	$3	Pulls trapped moisture and volatile organic compounds out.

This isn't the cheapest option, but spending $40 on the right supplies saves you from throwing away a $60 slow cooker. Keep these items in a dedicated under-sink bin for future emergencies.

Step-by-Step Removal

I'll be honest, this takes elbow grease. You are dealing with a biohazard on a porous surface, so half-measures won't cut it. Follow these six steps exactly as written to ensure your food is safe to cook in this vessel again.

Step 1: The Cold Water Pre-Rinse

Take the ceramic insert to your sink. Turn the tap to the coldest setting. Rinse the interior walls to wash away microscopic particulate matter. Do not use a sponge yet. Sponges harbor bacteria, and you don't want to cross-contaminate your kitchen sink area. Let the cold water run for a full 60 seconds, then dump the water down the drain and flush it with a cup of white vinegar to protect your plumbing.

Step 2: The Enzymatic Soak

This is the most critical step. Spray the entire interior of the ceramic insert with Nature's Miracle Urine Destroyer. You need to saturate the surface, especially around the rim and the bottom corners where waste pools. Let it sit for exactly 20 minutes. The enzymes need this time to literally eat the organic compounds. If you rush this step, your slow cooker will smell like a barnyard the next time you heat up a pot roast.

Step 3: Scrubbing the Ceramic Insert

After the 20-minute soak, spray the Dawn Platinum Powerwash directly over the enzymatic cleaner. Take your soft-bristle brush and scrub the interior in circular motions. Pay special attention to the unglazed ring near the top rim of the Crock-Pot. That rough, unglazed ceramic band acts like a sponge for odors. Scrub that band for at least two full minutes. Rinse thoroughly with warm water until the suds completely disappear.

Step 4: Tackling the Glass Lid and Silicone Gasket

If you own a Crock-Pot Cook & Carry model, your lid has a silicone sealing gasket. Silicone absorbs odors aggressively. Remove the gasket if your model allows it. Soak the gasket and the glass lid in a basin of warm water mixed with 1/2 cup of baking soda for 30 minutes. If the gasket is fixed, use a soft toothbrush dipped in the baking soda paste to scrub the rubber crevices. Rinse and dry completely with a microfiber cloth.

Step 5: Sanitizing the Heating Base

Inspect the metal heating base. If any liquid seeped down the sides into the heating coil housing, you have a serious problem. Unplug the unit. Take a Lysol wipe, wring it out until it is barely damp, and carefully wipe the interior metal walls. Never pour liquid directly into the base. Use a dry cotton swab to clean the tight corners near the heating element. Let the base air dry in a well-ventilated room for 48 hours before plugging it back in.

Step 6: The Oven Bake-Off

To guarantee zero lingering odors, use heat to destroy remaining volatile organic compounds. Place the clean, dry ceramic insert into your kitchen oven. Set the oven to 200°F. Bake the stoneware for two hours. This mimics the slow cooking process and burns off any invisible residual bacteria or odor molecules. Let it cool completely inside the oven before removing it.

Alternative Methods

Sometimes you don't have enzymatic cleaners on hand, or the stain is particularly stubborn. Here are three backup methods I've used when my primary supplies ran out.

Method 1: OxiClean Max Force Soak

Fill the ceramic insert with hot water and add two scoops of OxiClean powder. Let it soak overnight for at least 12 hours. The oxygen bubbles help lift physical stains from the ceramic glaze. This method is excellent for visual discoloration, but it doesn't neutralize uric acid as effectively as enzymes. You will still need to do a baking soda scrub afterward to kill the smell.

Method 2: Diluted Bleach Solution

Mix 1/2 cup of standard household bleach with 1 gallon of cold water in the insert. Let it sit for 15 minutes. Bleach is a powerhouse disinfectant that will kill any lingering pathogens instantly. However, you must never mix bleach with ammonia or urine, as it creates toxic chloramine gas. Ensure the insert is thoroughly pre-rinsed of all physical waste before using bleach. Rinse the pot five separate times with fresh water after the soak.

Method 3: White Vinegar and Baking Soda Volcano

Sprinkle a thick layer of baking soda over the bottom of the pot. Pour two cups of white vinegar over the powder and let it fizz for 10 minutes. The mechanical action of the bubbling helps lift debris from the pores. I'll be honest, this is weak for heavy feces odors, but it works in a pinch for minor accidents or if you're just trying to refresh a pot that smells slightly off.

Prevention Tips

Once you've survived this cleanup, you'll want to ensure it never happens again. If you have pets who track mud everywhere or cats that seek out warm, enclosed spaces, you need physical barriers.

• Store with the lid inverted: Always store your slow cooker with the glass lid placed upside down inside the ceramic pot. This eliminates the dark, cave-like environment that cats find irresistible.
• Use an appliance strap: Buy a $10 silicone appliance strap from Amazon to bind the lid to the base. This stops toddlers from opening the pot and prevents pets from knocking the lid off.
• Deploy a pet deterrent: I use the PetSafe SSSCAT compressed air deterrent ($40). Place it on the counter next to the slow cooker. If your cat jumps up and approaches the pot, the motion sensor releases a harmless burst of air that trains them to stay away.
• Keep it in a cabinet: Don't leave the slow cooker on the counter when not in use. Store it on a high shelf in a pantry where animals and small children cannot access it.

FAQ

Can I just run the ceramic insert through the dishwasher?

You can, but I strongly advise against doing it immediately after a feces incident. Dishwashers use high heat that can actually bake residual proteins and bacteria into the microscopic pores of the stoneware. Run the manual cleaning steps first, then use the dishwasher for a final sanitizing cycle.

How do I know if the heating base is ruined?

If liquid feces seeped down into the heating coil housing, you'll likely smell burning organic matter the next time you plug it in. Unplug the unit immediately and inspect the interior with a flashlight. If you see crusted debris inside the metal housing that you can't reach with a cotton swab, the base is unfortunately a biohazard and needs to be thrown away.

Will the smell ever completely go away?

Yes, but only if you break down the uric acid crystals rather than just masking them. Enzymatic cleaners are the only products that actually digest the odor-causing bacteria at a molecular level. If you still smell a faint odor after cleaning, repeat the enzyme soak and finish with the 200°F oven bake method.

Should I just throw the whole slow cooker away?

I'll be honest, if it's a cheap $20 model and the mess leaked into the heating base, just trash it. However, if you have a high-end Crock-Pot or a Hamilton Beach model with a removable ceramic insert, it is absolutely worth saving. The ceramic insert and glass lid can be fully sanitized, saving you $50 or more on a replacement.
